The manuals all say that it doesn't matter the distance between the dish and the switch and/or the receiver and the switch as long as the total run from the receiver to the dish doesn't excede 200ft. On a side note, I have seen runs far excede 200ft though. I would think the limiting factor in long runs would be the voltage loss and not the signal loss. If I had a run over 200ft then I would make sure that I used Solid Copper Center conductor RG6.
